Aircraft Extrusion Tolerances

Profile tolerances are a key considerations in designing extrusions. Aircraft Extrusion Company understand the mechanics of working with aluminum. For each part we manufacture, we consider wall thickness, profile circumscribing circle size, location of dimension on the profile and the type of profile. We are also able to match the tolerance specifications with the right extrusion press size. While the aluminum industry provides standard dimensional tolerance guidelines for extruded aluminum profiles, flatness and twist, contours, straightness.

How we inspect

widerOur AS9100 certified quality management system allows us to provide the consistency and traceability required in the aviation industry. We pride ourselves on our document control procedures which ensure all required documentation is controlled, distributed, and maintained appropriately. Our planning and scheduling department ensures that projects flow smoothly through the shop and all required materials are available when needed.

In-House Design Team

We are proficient in SolidWorks and Autocad and can translate engineering drawings and designs. We work with designers, engineers and buyers daily. Provide cost analysis and feasibility studies for commercial and aerospace grade aluminum. Providing over the phone quotes on most custom from simple to complex. We can discuss feasibility, die charges and lead times for Extrusions and tubes.
